Jump Menu opening up in new page

I have a jump menu on my web page and want the links on it to open in a new
page. Any ideas? I tried tweaking the code as follows:

onChange="MM_jumpMenu('parent',this,0) //original

onChange="MM_jumpMenu('_blank',this,0) //tweaked

Didn't work. Any ideas. Thanks in advance.

Resolved.

<select name="menu1"
onChange="MM_jumpMenu('window.open()',this,0)">
